Grax shows you how to build a raft to hold an action cam. Perfect for floating down a river, lake, sea, etc. He is using an SJ4000 action cam, but any kind of action cam (like the GoPro series) should work just fine as well.

This is a test recording of the SJ4000 when attached to a guitar. I recorded the action cam at 1080p. I am splicing footage between the SJ4000 and the Nikon D5300 DSLR camera and then I the quality to 720p. I did all this using Adobe Premiere 5.5.
